Great battery pack for flash power(repost)

cyrilng · 4th January 2003

I've been using the UnderDog & PocketDog flash batteries for the past three years & I think they have excellent performance & value for money.

The UnderDog batteries are basically 6 volt/1.3 Amp/hr lead-acid, rechargeable flash batteries that can be attached to the bottom of the cameras or motor drives tripod socket. The PocketDogs are slimmer & lighter as they come without the screw-mount & can be carried in your pocket.

The UnderDog weighs 350g, measures 9.5x5.8x3.4cm & the PocketDog is 310g & measures 9.6x5.8x2.6cm.

Using 400ASA film shooting at f8 indoors, one battery can last around 10-15 rolls easily with super fast recycle times.

These are just plain old lead acid batteries with no memory-effect & no fancy LEDs or power indicators but they do the job & are value-for-money IMHO.

Please note that the batteries don't come with cables to connect to your flash but you can buy & use Quantum Battery 1+ cables that correspond to your brand & model of flash which are available locally at shops like Fotoguide for around S$90. If you prefer the Short Leash cable (see bottom photo) that is of a shorter length & designed for use with the UnderDog attached to the base of your camera & to do away with an unnecessarily long & cumbersome cable length, then you can order it for US$55 directly from Jon Falk Lights.

You can buy just one battery & a charger but the batteries are also sold in a kit consisting of two batteries & a charger as it's recommended to have one in use & one as a spare. You'll also save US$5 if you order the kit.

Please see http://www.underdog-battery.com/product.htm for the full range of products & here for the US price list & order form http://www.underdog-battery.com/order.htm

(If you don't think they are as good as I find them, at least check out Jon Falk's website & read the FAQ & other stuff there, it's really funny. He's a real nice guy too, actually sent me a nice Christmas present after my last order.

U guys can consider the Lumedyne series that I have been using for many many years now that is really good and may not be as expensive as this Underdog thing. Although I can't really remember what price i paid it for :P Go check with Cathay Photo.

That one should be for DSLR bodies + flash only.

Is the Lumedyne as compact as this? Anyone know how much it costs?

vince123123 · 23rd January 2003

Well its not as compact, but that also means that the capacity is greater, ie more charges. Forgot costs how much liao but i think with charger n cable n everythign cost me abt 300+

OK, so it means about the same cost but less compact than the Under/PocketDogs but I think the Lumedynes have LEDs to show remaining charge levels right while the PD/UDs don't. I can usually tell that the charge level is dropping from the sound the flash makes when recycling which of course becomes slower also. Personally I prefer my equipment compact & light as possible, so my vote goes for the PocketDogs.

vince123123 · 24th January 2003

actaully Im not sure abt the lumedyne cost :P go check at ur cathay outlet. but like i said im sur ethe capacity is higher due to its bigger size....however it snot bigger by a lot cos its in a slim tower-like shape, as in not big n fat kind, but just perhaps longer. wont make much diff cos when u clip to ur belt whether long or short oso take hte same amt of belt space

I think when you add up the cost of the Lumedyne battery, charger & cable (I believe it can use Quantum 1+ cables too) comes up to about the same or more.

The PocketDog is the smallest & most compact flash battery pack around that I know of.
